I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This happens in later versions of Excel. We believe it has something to do with the additional complexity programmed into the application and that causes Excel to take longer to initialize it's various components which can cause issues with VBA code running at the same time. The workaround is to use the OnTime command to delay VBA processing until after Excel has settled down.

Private Sub Workbook_Open ()
    Application.OnTime Now(), "ThisWorkbook.AfterOpen"
End Sub

Public Sub Workbook_AfterOpen()
    Application.OnKey "{F10}", "changeToVal"
